In a nutshell

Soil organisms have a significant influence on key soil functions. However, despite their important role, data on soil biodiversity in Switzerland is still very limited, and only a few surveys have been conducted on biodiversity in deeper soil layers.
The main objective of the dissertation is to survey the biodiversity of microorganisms and mesofauna across all soil layers at various locations in the canton of Graubünden using molecular and imaging technologies. At selected locations, molecular methods and X-ray tomography will be used to investigate the influence of soil structure on various organisms.
The different perspectives on soil biodiversity in both the topsoil and subsoil represent an important milestone in better understanding the soil ecosystem and preserving soil biodiversity.
